<P>PROBLEM TO BE SOLVED: To smoothly incorporate a rolling element into a pocket while suppressing improper deformation of a claw part even when the positional deviation of the rolling element occurs during the assembling of the rolling element, to prevent deterioration in elastic deformation characteristics of the claw part, and to suppress the capacity reduction of a grease pocket. <P>SOLUTION: The rolling bearing includes an inner ring and an outer ring, the rolling elements rollably disposed between both rings, and a cage 33 which is disposed between both rings and holds the rolling element rollably in a state in which the rolling elements are evenly spaced in the circumferential direction. The cage includes: a body part 34 which is formed into an annular form and has a plurality of recessed pockets P into which the rolling elements are inserted; and a pair of claw parts 35 for holding the rolling elements inserted into the pockets rollably. On the outer surface at the tip of the claw part, a guide projection 40 is formed which projects toward the diametrical direction-outside of the pocket, which guides the rolling element to the pocket side during the assembling of the rolling element. <P>COPYRIGHT: (C)2012,JPO&INPIT |
